Interesting. I usually drill 3/16" holes about 1/4" deep in the aluminum intake ends and then fill the holes with silicone before running the bead on the block surfaces.F100builder wrote:...Another thing that I usually do is put dimples along the rails with a sharp center punch and a light tap with a ball peen hammer. This gives the silicone 'grip' and keeps it from pushing out like the cork and rubber gaskets almost always do (or at least leak). Below is a pic of my stroked small block. If you look closely, you can see the dimples along the front and back rails...
Also a good idea...a little more work though I suppose.BobbyFord wrote:Interesting.
